| 摘 要： | 建立了一个原子分子碰撞辐射动态模型，用以模拟Ａｒ－Ｈｇ介质阻挡放电的动力学过程．模型中考虑了原子－原子，原子－准分子以及准分子－准分子之间的相互作用．计算了１１种状态粒子的占居数随时间的变化．给出了微放电等离子体中原子、分子的演化图象．此外，对汞的两个共振激发态以及汞的准分子（Ｈｇ２和Ｈｇ３）形成情况也作了研究．

| Abstract: | numerical dynamic collisional radiative atomic and molecular model(CRAM) is developed to simulate the kinetics in a single microdischarge of a Ar-hg dielectric barrier discharge(DBD).The energy transfer among atoms and excimers (Hg2 and Hg3) are taken into account.Altogether 11 species' population as a function of time are calculated. The model is nonstationary and decribes the evolution of the plasma phase in a microdischarge perfpr,omg particle reactions induced by the excessively strong streamer breakdown in the gap. Further discussed Is the formation of the excited hg atoms on two resonant levels(61 P1 and 63 P1) and the excimers as well. |
